The electron spin resonance of a gamma-irradiated single crystal of thiodiglycolic acid was measured at room temperature at 9 kMc. From the analysis of the anisotropy in the spectroscopic splitting factor and in the nuclear hyperfine in- teraotion constants, a model of tbe free radical HOOC -CH/sub 2/--S- -CH--COOH is proposed. In this free radical, the electron spin density is mainly in a pi orbital, about 60% of which is the p orbital of the CH carbon, 2% is the 1s orbitals of the CH/sub 2/ hydrogens, and 22% is in the p orbital of the S.
